operator==operator!= (直到 C++20)

 

定义于头文件 <memory_resource>
bool operator==( const std::pmr::memory_resource& a,                  const std::pmr::memory_resource& b ) noexcept;	(1)	(C++17 起)
bool operator!=( const std::pmr::memory_resource& a,                  const std::pmr::memory_resource& b ) noexcept;	(2)	(C++17 起) (C++20 前)

比较 memory_resource a 和 b 是否相等。两个 memory_resource 相等当且仅当从一个 memory_resource 分配的内存可以从另一个释放，反之亦然。

!= 运算符由 operator== 合成。

(C++20 起)

返回值

1) &a == &b || a.is_equal(b)

2) !(a == b)
